leonid [27]

Answer:

1. Mitochondria

2. Chloroplast

3. the formation of eukaryotic cells

4. DNA

Explanation:

The theory of endosymbiosis was proposed by the Lynn Margulis in 1967 which suggested that the eukaryotic organelles like the mitochondria and chloroplast evolved when another prokaryotic cell engulfed the prokaryotic bacteria.

The mitochondria were formed when the chemosynthetic bacteria were engulfed by the bacteria and the engulfed bacteria formed a symbiotic relationship. Similarly, the chloroplast was originated in the same way when the photosynthetic bacteria were engulfed by another prokaryote.

The evidence which supports their ar:

1. The same size of the organelles to the bacteria

2. The presence of the circular DNA of the organelles like bacteria  

3. The similarity in the 30s and 70s ribosomal subunits.

stiks02 [169]

Answer:

<u>B. Animals do not use carbon dioxide as an energy source; they use carbohydrates.</u>

Explanation:

The most readily form of energy that an animal requires is carbohydrate molecules. Monosaccharide carbohydrates can be easily broken down and hence are the best sources of energy. Carbohydrates are broken down in the process of cellular respiration to generate ATP. ATP is the energy driving molecule which is required by every cell of an organisms body to carry out its normal metabolic functions. Hence, animals use carbohydrates as a source of energy, not carbon dioxide.

The main purpose of wildlife (movement) corridors is to
Kryger [21]
I believe the main purpose of wildlife (movement) corridors is to connect two otherwise isolated populations. Wildlife corridors are links of wildlife habitat that joins tow or more larger areas of similar wildlife habitat. They are very critical for the maintenance of ecological processes such as allowing the movement of animals and the continuation of viable populations.
